The Multiquip 49997 is a genuine OEM U-Bolt 5/16-18 x 2-1/2 x 3-3/16 designed for Multiquip Water Trailer models including the WT5HP, WTE5HP, and WT5HPSG series. As a direct OEM replacement, this U-bolt carries the exact thread pitch, leg span, and bend radius specified for these units, so it installs without rework or shimming. Sourcing the correct-specification hardware is critical on water trailer applications where fasteners bear continuous load and vibration stress. DHS Equipment stocks this part ready to ship so your trailer stays on the job.
Key Features
- Correct Thread and Dimensional Spec — Manufactured to the exact 5/16-18 thread pitch, 2-1/2" leg span, and 3-3/16" inside width called out for these water trailer mounting points, eliminating guesswork at installation.
- Genuine OEM Construction — Produced to Multiquip's material and hardness standards, giving this U-bolt the tensile strength needed to maintain clamping force under continuous road vibration and load cycling.
- Direct Hardware Replacement — Matches the original mounting configuration on WT5HP, WTE5HP, and WT5HPSG water trailers, so the fastener seats flush and torques to spec without adapters or modified hardware.
- Maintains Structural Clamping Integrity — A correctly sized and torqued U-bolt keeps axle, spring, or tank mounting brackets firmly secured; an undersized or worn fastener allows shift and wear that accelerates damage to surrounding components.
- Verified OEM Part Number — Part number 49997 cross-references directly to Multiquip's published parts documentation for these water trailer models, confirming you are ordering the right hardware the first time.
A U-bolt is a threaded fastener shaped in a U profile, used to clamp and secure components such as axle assemblies, spring packs, or structural brackets to a trailer frame. The two threaded legs pass through a mounting plate and are secured with nuts, drawing the clamped component tight against the frame rail. Because U-bolts carry both the static weight of the assembly and the dynamic shock loads generated during transport, correct sizing and material grade are essential — an incorrect thread pitch or leg length prevents proper nut engagement, while an undersized bend radius creates stress concentrations that can lead to fastener fatigue and sudden loss of clamping force.
